Security Thread: An embedded security thread running vertically through the bill displays "THE UNITED STATES OF AMERICA" and glows orange under ultraviolet light, making counterfeiting substantially more difficult.
Color-Shifting Ink: A small metallic image in the lower right corner changes color from copper to green when tilted, representing one of the most advanced anti-counterfeiting features implemented in 2000.
Watermark and Microprinting: Subtle watermarks matching Hamilton's portrait and microscopic text reading "THE UNITED STATES OF AMERICA" are visible when held to light, requiring sophisticated equipment to replicate accurately.
Dimensional Specifications: The bill measures 6.14 inches long by 2.61 inches wide and is printed on a specialized blend of 75% cotton and 25% linen, creating distinctive texture and durability far exceeding regular paper.
